On hardware a load costs an open and a read of the file, plus about 1ms and 30us per KB of loader work (pspautotests threads/scheduling/callcosts), with the caller waiting throughout. It now charges sceIoOpen's and sceIoRead's estimates for the file plus that, instead of a flat 500us. Also notes why sceKernelLoadModuleByID fails from a game's own fd on ms0: or host0: on hardware, which we don't emulate. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
